Application filed May 1'7, 1906. Serial No. 317.266.

Be it known that I, J ULIUS E.;NA0H0D, a citizen of the United States, residing in the city and count of Philadel hia," State of ave invente certain new and useful Improvements in Envelop-Seal- I ing Machines; and I do hereby declare the following to'be a full, clear, and exact description of the invention,"such as. will enable Io'others skilled in theart to which it appertains to make and use the same.

: The invention relates to apparatus for sealing envelops, and belongs generally to that type of envelop-sealing machines deiscribed and claimed in- Letters'Patent granted to me vMarch 27 1906, and numbered 4 816,175- and 816,176, res ectively, and has for its objects to improve t e means for moistenlng the flaps of the envelops as they pass through the machine, as well as the means for pressing the flaps against the body of the enveloppnas the latter are discharged from the mac e, said improvements being particularly-adapted to machines of'this general the accompanying drawings, Figure 1 is Fig. 2is a plan viewthereof, the top plate being ar- I tially broken away. Fig. 3 1s a longitu inal 0 section on the irregular line 3 3, Fig. 2.

I Referring to the drawin s, a indicates the casing of t 1e apparatus,w 'ch may be conveniently constructed, as in my prior patents hereinbefore referred to, said casing consist- 3 ing of a base 6, side and end walls, and a top constituting a platform 0, over which the body of the envelop is passed. The side wall '5 on the left of thecasing serves to guide the flap as it enters the machine and hold the 0' same with its gummed side in engagement with the moistening device. Between the side wall t and the end wall I of the casing I there is provided a guide-wall k, having a surface twisted or skewed both longitudinall 5 and transversely, so that said guide-wa --sprmging from the side wall 'i gradually merges into a plane parallel with that of the platform e, whereby as the envelop is drawn across the latform e the flap after having so been asse over themoistening device is engage by the twisted or skewed guide-wall 7c until it is brought into substantial aranaism with the body of the envelop, from which I it is separated by the thickness of the plat- 'tener tended to impede the giSSSLgB of the enplished by providing .as a moistening device a vertical rol consisting of a shaft 6, journaled in the latform e at one end and in a bearing located on the bottom of the reservoir e at and a pad of absorbent materialviz., felt or the likesurrounding said core and dipping into the reservoir. Said reservoir is conveniently formed as a closed pan e, attached to the under side of the casing by suitable brackets 1', and providedwith a circular opening in .its top, throu' hwhich the moistening-roll extends, and ad apt'ed to' receive a body of cotton fiber or similar absorbent material which holds sufficient water to keep the absorbent pad on the roll in the properly moist condition and nevertheless prevents the water s illingwhen the machine is moved. In ord cr to supply the pan or reservoir with water, there is provided in the side of the base I) a fillin -opening 9', which communicates with the c osed an or reservoir e and also serves as an ove ow should too much water he supplied. The provision of the absorbent cotton within the reservoir leaves but little free water, yet provides moisture insufficient quantity to supply the absorbent felt on the roller continuousl as demanded. Mounted on the inside of t e wall t by means of suit- "Iight sheet metal which presses against the moistening-roller, and as the flap of each en- .velop is caused to pass between said spring and the roller it will be apparent that-the spring holds the flap in contact with said roller with just sufficient force to causethe flap to absorb the proper amount of moistur to soften the adhesive.

Should it be found necessary to remove the'roller for adjustment or repair or renewal of the-felt covering, it is necessary only to detach the reservoir, which will permit the roller to drop out of its bearings.

III-order to avoid the tendency of the encharged from the final sealing devices to accommodateenvelo s of various and varying of these difficulties. This has been accomthicknesses and a so to facilitate the entry 7 Inasmuch as a stationary WiCkfllkGfilOiiZ of 'flie envelop between thecoacting members the other, a core 0', secured to the said shaft, I

able screws n is a broad fiat spring made of velops to crease and buckle as they are dis- IIO ' s ring and of the sealing or presser devices at the discharge end of the machine, -I provide an especially eflicient means for pressing the flap against the body to complete the sealing operation. This resser device consists of a bristle-brush t, mounted upon a metal spring .9, which is attached to the coverp ate n of the machine by screws it, which spring is adjustable by means of a tensionscrew 10, e aging a nut 'w on the end of said earing against the cover-plate n.

he bristle-brush 6 lies above and cooperates with a rollerr, -mounted in brackets q, secured to the end plate Z of the casing a, one

of said brackets being somewhat longer than the other, so that the roller, 1" and the brush t coacting therewith lie at an angle to the direction of travel of the fla throu h the machine. The inclination. o the ro ler to the direction of movement of the envelop insures the enveloplpassing gradually between the brush and t e roller instead of moving abru tly into contact. with the two ressing mem ers, as in constructions hereto ore produced, and which resulted in a high resistance and op osition to the movement of the envelo in t e final sealing operation. The brush ristles are arranged vertically and substantially radially to the roller, and they .readily yield locally to such variations in thickness as would be occasioned by coins or other small irregular articles contained in the envelo s. In order to hold the brush up to its wor and prevent the bristles whipping backward, an auxiliary spring plate :1), attached to the under side of the brush-supporting spring 8, engages the inner row of ristles near their lower ends. The brush crigperating with the roller excercises a more u orm pressure on the flap, and as this pressure is s read over a lar er area thanwould be possile with the older form of presser mechanism the final o eration of sealing is effected without wrinklin or creasing. By adjusting the tension of t e s ring 8 the degree of pressure between the rush and the roller may be regulated to the varying conditions of the work.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In an envelop-sealing apparatus, the combination of a casing having a platform for sup orting the body of the envelop, a lateral wa l at an angle to the latform for guiding the fla a moistening evice adjacent to said latera wall, a guide-wall for closing the flap on the body, a guide at the discharge end of the casing, and a brush cooperatingwith said 1ide to press the flapagamst the body.
